The Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction (CWC) is a multilateral treaty which obligates its signatories to destroy their chemical weapons within ten years of the treaty's entry into force. It also bans the development, production, stockpiling, transfer, and use of chemical weapons. In addition, there is a special obligation to destroy weapons abandoned by one State Party to the CWC on the territory of another State Party. This paper identifies some of the logistic, technical, legal, and financial problems in destroying abandoned chemical weapons (ACW) in China.
